Hi friend,
This is what I got from Payssion during our last communication:
I feel sorry to tell that, currently we have no credit card payment solution. We focus on local payment for places where credit cards are not popular. If you're looking for cards, we may not be suitable provider.
Please bear this in mind.
Try Skrill. They support a lot of countries. I am currently in discussions with them.
Edit: just checked Skrill reviews on trustpilot and there are quite a lot of negative ones. So be careful.
